Having read your question I got out my IR Temp Gun, and took some readings. I've been using my X301 for about 4 hrs straight so far today. Here are the temps:
85 degrees F @ center of keyboard
81 " " @ center of touchpad
80 " " @ left front & right front palm rest
87 " " @ left rear corner of keyboard
83 " " @ right rear corner of keyboard
91 " " @ center of bottom surface
84 " " @ center of bottom below touchpad
90 " " @ right rear corner of bottom
83 " " @ left rear corner of bottom
82 " " @ left front corner of bottom
83 " " @ right front corner of bottom
I compared these temps to the ones I recorded for my X300 and they are nearly the same +/- 2 or 3 degrees. Strikingly similar. Over all to the touch, both of my X3xx series ThinkPads are cool, quiet and quite fast (given the processor speed) I could not be happier.
Hope this helps
Cheers...
